The city of Conroe, Texas, is building a $60 million Central Wastewater Treatment Plant that will be designed to handle up to 12 million gallons per day. Stiver Engineering provided design services for a 38-foot ID Lift Station for the new Central Wastewater Treatment Plant in Conroe, Texas. Our work included sinking calculations and the finite element analysis of the exterior walls and the caisson bottom slab.

Stiver Engineering prepared a caisson cutting edge design for a wastewater lift station replacement project in Redmond, Washington. In addition to the caisson cutting edge design, Stiver performed skin friction calculations for the pour heights and proposed wall thickness to check the safety factor for sinking.

Stiver Engineering was retained to provide structural design through a contractor with two caisson designs for the City of Charleston, South Carolina. We designed the reinforced concrete structures to be poured in lifts and sunk into the earth until the cutting edge of the caisson reached the design elevation. Our engineers also provided the client with a braking system design that could be activated if the caisson had difficulty stopping at the design elevation.

Stiver Engineering provided both mechanical and structural plans to the contractor for construction.

Stiver Engineering was retained to provide structural design to a contractor in Baton Rouge, Louisiana with a caisson design for wastewater facility upgrades in a commercial area. We designed the reinforced concrete structure to be poured in lifts and sunk into the earth until the cutting edge of the caisson reached the design elevation. We also provided both mechanical and structural plans to the client for construction.
